在分析不同色温恒星光谱分布特征的基础上，建立恒星光谱模型，计算色温差异引起的恒星定位误差。
In order to analyze the effect of color temperature in star sensor, the model of stellar spectrum was presented in this paper.
通过寻找绕行星轨道运行的母恒星中的摇晃，已定位了400多个行星。
More than 400 have been located by looking for the wobbles in parent stars that orbiting planets cause.
白矮星是具个性的，也是非常稀有(可能因为定位它们很困难)令人惊异的恒星，在上百个离我们的太阳最近的星系中只有八颗已知的白矮星。
Those are amazing objects in their own right, and also rather rare (perhaps because they're so difficult to spot) : there's eight known white dwarfs in the hundred nearest star systems to our sun.
卫星通过对每颗恒星反复观察进行定位。
The satellite fixes positions by making repeated observations of each star.
研究人员于2008年用哈勃望远镜定位到这颗行星，它围绕着一颗25光年之外的恒星公转。
Researchers using the Hubble Space Telescope spotted it in 2008, orbiting a star 25 light-years away.
RACID已经成功的应用于恒星追踪，天体导航应用，此时，指定的星体可以定位引导的读取和处理。
RACID's are successfully employed in star tracking and celestial navigation applications where only designated stars within the canopy of space are read and processed for positional vectoring.
系统可工作于两种模式：恒星目标检测定位模式和运动空间目标检测跟踪模式。
This system can work in two modes: fixed star detection mode and moving space target tracking mode.
